How to Setup Your Room for Atmos and Immersive Audio

I think this video by the Dolby Institute is targeted at professionals but the principals translate to the home. You’ll notice that they don’t use the ceiling speakers pointing straight down but bookshelves that are angled toward the MLP. The other thing you’ll notice is that all of the bed channel speakers are at the same height (that includes the center channel). At 16:00 minute in the video make sure to watch the part about room tuning, very helpful as to what DSP can and cannot do:

" I feel like money spent on this type of help (room treatments and acoustics) will be more valuable than any piece of gear you will ever buy"



So I just spen 2 hours redoing my “room perfect” DSP. I played Elton John’s “Sorry seems to be…” it sounded awful in Atmos and much bigger wider deeper in stereo. Is it possible my room sounds better without DSP I don’t even know if I can turn it off or maybe not movies sound great, why did the same song have such a poor showing in Atmos.

Hemispherical speaker are a great idea just like PZM microphones they don’t “see” the plain they are mounted to, makes a lot of sense.

The curve seems ok in real life speakers and microphones sound bad next to a big reflection is simply because of phasing, midrange (1K) usually gets the most noticeable damage this happens if a singer is standing to close to a music stand in the studio it makes a big difference when you lower or remove the stand, if that fails you put a fuzzy blanket over it. That curve is only a single frequency sine wave, music doesn’t look like that, in fact the curves we see on ARK and DSPs like that are just a representation of an averaging algorithm, sound doesn’t look like that only tones do, sound looks like pressure waves. I tried to use a chemical to show sound once, I was working to much, I should pursue it again now, I think I will.

@kota1 i forgot to mention fib. Numbers are cool, I’m curious how you can set them up without something like Protools, do you have something that lets you pan the signal between the speakers? How do you use the fib numbers?

DSP is limited in what it can do. If you post your measurements there will be a before and after graph and we can discuss.

I use fib ratios for placing seats, placing panels, not really for equipment.

The HST speakers place the woofer on the back, about 2 inches from the wall, facing it. Two tweeters angled out at left and right directions. It worked better for my room than traditional on walls.

Does this give you any ideas for your home atmos studio:

Studio D 1

Studio D – Dolby Atmos, Post-production & Mastering

Studio D is a our new mixing, mastering, and music production studio featuring an Avid S6 48-channel digital mixing console with Dolby Atmos 7.4.1 surround sound designed by world-reknowned studio designer John Storyk. 


You were thinking about dropping six figures on some speakers or getting some new gear. The answer you are looking for is in the post above. How many clients would you get if you took that budget and invested it to have a guy with a rep like Storyk design your home studio?

"The sound guy from Titanic will mix your content in immersive audio in his studio designed by World Renowned Studio Designer_______________ (Storyk, etc)."

That would immediately give you creds in BOTH communities, pro and audiophile. Case closed.
